FEEDING DEVICE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 437,784, dated October7, 1890.

Serial No. 326,175. (No model.)

To all whom it may concern.-

Be it known that I, GEORG MEISOHNER, a citizen of the Empire of Germany,residing at Freiburg, in Germany, have invented a new and useful Feedingand Presser-Foot Device for Sewing-Machines, of which the following is aspecification.

My invention relates to improvements in feeding and presser-foot devicesfor sewingmachines; and the objects of my improvements are, first, toprovide the presser-foot with a rotary feeder acting from above theneedle-plate; second, to provide means for actuating the rotary feederintermittently from the needle-bar; third, to afford facilities forvarying the amount of feed. I attain these objects by the mechanismillustrated in the accompanying drawing, which represents an end view ofthe sewing-machine head furnished with the improved feeding andpresserfoot device.

Similar letters refer to similar parts.

a is the needle-bar; a, the needle; 0, the presser-foot;i, theneedle-plate; 7c, the presserfoot bar.

To the presser-foot c is pivoted an arm Z, the free end of which isarranged to be raised and lowered by means of a screw Z, passing throughthe same into the presser-foot c. On the arm Z is mounted a toothedfeed-wheel f, the periphery of which projects below the presser-foot 0,so as to act from above upon the material under operation on theneedleplate 2', and which is intermittently rotated from the needle-bara by means of a lever d and pawl g. On the lower end of the presserfootbar 7c is suitably fixed a sleeve 6, to which is pivoted the lever d,carrying at its lower end the pawl g, in engagement with the toothedfeed-wheel f and its upper end being under the influence of a spring (Z,attached to the sleeve e. In lieu of forming the presser-foot bar It andpresser-foot c in one piece, they may be formed separately and connectedtogether by means of the sleeve 6.

The needle-bar a near its lower extremity is furnished with the screw1), which secures the needle a thereto, and on ascending comes intocontact with the upper end of the lever (Z, which causes the latter torock and the pawl g to impart a partial rotation to the toothedfeed-wheel f, the spring (Z bringing the lever (Z back to its normalposition on the needlebar a descending.

The amount of feed to be effected by the wheelf may be varied as desiredby bringing it nearer to or farther away from the pawl g through raisingor lowering by means of the bar Z and screw Z. I.

The combination of the presser-foot and retary feed describedfacilitates a more regular feed and prevents the displacement of theparts to be united.

What I claim as my invention, and desire to secure by Letters Patent, is

In sewing-machines, the rocking lever d, carried by the presser-bar k ona sleeve 6, the upper end of which lever (Z is acted upon by theneedle-screw b and spring d and thelower end furnished with a pawl g, incombination with the rotary feed-wheel f, mounted on a radiallyadjustable arm Z, pivoted to the presser-foot c and adapted to vary theaction of the pawl g on the feed-wheel f, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of September, 1889.
